DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for bonding a surface covering material to the inner and outer wall surfaces, ceilings, columns and beams of a structure such as a building, or the surface of a wall material or a ceiling material used for them. The present invention also relates to a foamed refractory adhesive for improving fire resistance and a finishing method using the same.

[0002]

2. Description of the Related Art Conventionally, inner and outer wall surfaces of structures such as buildings,
A surface material such as a tile, a stone material, or a wallpaper may be attached to a surface of an object to be bonded such as a ceiling, a column, a beam, or a wall material or a ceiling material used for the ceiling, a column, and a beam. This is to improve the protection and design of the adherend. When the surface covering material is bonded to the adherend, cement, a synthetic resin, or an adhesive mainly containing cement and a synthetic resin is used. These adhesives
The adhesiveness between the surface material and the material to be bonded is excellent, and the bonding workability is excellent.

When tiles and stones are used, generally, an adhesive mainly composed of cement is often used. Since the adhesive containing cement as a main component is a powder containing cement as a main component, it is mixed with water immediately before using the adhesive, and is easy to handle. Further, since the adhesive containing cement as a main component is a powder, it can be easily transported and stored, and is easily available. Further, since it is mainly composed of inorganic cement, it is flame retardant and has fire resistance.

In the case of using a wallpaper or a sheet-like covering material, an adhesive mainly containing a synthetic resin as an organic component is often used. Many adhesives containing a synthetic resin as a main component have flexibility after the adhesive is cured. Because it is flexible, it follows the movements that occur in the structure, and the surface covering material attached with an adhesive mainly composed of synthetic resin is less likely to crack, and furthermore, the surface covering material is peeled off. It can be reduced.

[0005]

However, since the adhesive containing cement as a main component is not flexible, it cannot follow the movement of a structure, and is adhered by the adhesive containing cement as a main component. Cracks may occur in the surface material that has been applied. In addition, since the adhesive containing cement as a main component is hardened by the hydration reaction of the cement, the hardening starts when water is added, and the pot life is limited.

[0006] Many adhesives containing a synthetic resin as a main component do not have flame retardancy because the synthetic resin is flammable, and often have poor fire resistance. The present invention has been made by paying attention to the problems existing in the prior art as described above.
The purpose is to improve the heat insulating property of the adherend by foaming the adhesive applied to the adherend, to obtain fire resistance, and to be flexible, Further, a finishing method using the same is provided.

[0007]

In order to achieve the above object, a foamed refractory adhesive according to the present invention comprises a synthetic resin, a flame-retardant foaming agent and a polyhydric alcohol. is there.

In the finishing method according to the second aspect of the present invention, a foaming refractory adhesive containing a synthetic resin, a flame-retardant foaming agent, and a polyhydric alcohol is applied to an object to be adhered, and then a covering material is attached. is there.

A finishing method according to a third aspect of the present invention is the finishing method according to the second aspect, wherein the covering material has flexibility and waterproofness.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. The foamed refractory adhesive contains a synthetic resin, a flame-retardant foaming agent, and a polyhydric alcohol. The foamed refractory adhesive foams by heating in a fire or the like, forms a heat insulating layer, and suppresses a rise in the temperature of the adherend, thereby imparting fire resistance to the adherend.

First, the synthetic resin is a main component of the foamed refractory adhesive, and is a binder for bonding the adherend and the surface covering material. Examples of the synthetic resin include a melamine resin, an acrylic resin, an alkyd resin, a vinyl chloride resin, a vinyl acetate resin, a urethane resin, an epoxy resin, a silicone resin, and a polyester resin.

These resins may be used alone, or may be copolymerized, and may be used as a mixture. Examples of the form of these resins include those dissolved in an organic solvent, those dispersed in a weak solvent, and those dispersed in water as an emulsion, and any of these forms can be used.

When an adhesive dissolved in an organic solvent or dispersed in a weak solvent is used as an adhesive, the organic solvent as a solvent is volatilized at the time of curing and spreads in the air. Not preferred. However, those dispersed in water as an emulsion are those in which water evaporates when the adhesive is cured, and are preferably used without polluting the atmosphere and the like. Furthermore, a synthetic resin emulsion obtained by dispersing a synthetic resin in water as an emulsion is easily available, has excellent physical properties such as water resistance as an adhesive, has excellent workability, and is easy to manufacture an adhesive. It is.

Glass transition temperature (Tg) of the synthetic resin
Is preferably in the range of −30 ° C. to 50 ° C.,
A range of 0 ° C. is more preferred. When the temperature is lower than −30 ° C., when the temperature in the atmosphere increases, the attached outer cover material may shift. When the temperature is higher than 50 ° C.,
Since there is not enough flexibility, it is impossible to follow the movement of the structure, and cracks may occur in the pasted covering material.

The glass transition temperature (Tg) is -20 ° C. to 4
The adhesive made of a synthetic resin in a temperature range of 0 ° C. is a flexible and well-balanced material that does not cause a displacement of the attached surface material. Further, the flexibility of the cured adhesive can be controlled by adding a plasticizer. The amount of the plasticizer varies depending on the required flexibility, the type of the additive, the type of the synthetic resin to be added, Tg, and the like. When the Tg of the synthetic resin is higher than 60 ° C., the amount of the plasticizer to be added increases, and the physical properties such as the water resistance of the cured adhesive may decrease.

The decomposition starting temperature of the synthetic resin is 250 ° C.
It is preferable that the content is not more than 50% by weight and not more than 50% by weight and not more than 90% by weight of the total solid by 300 ° C. Those having a decomposition initiation temperature of 250 ° C. or higher and those decomposing only by 50% by weight or less of the total solid content by 300 ° C. prevent the flame-retardant foaming agent and the polyhydric alcohol from dehydrating and condensing, thereby failing to form a sufficient foamed layer. 90 wt% of total solids by 300 ℃
%, The foamed layer becomes brittle due to excessive foaming, and easily falls off.

Further, as a flame-retardant foaming agent described later,
The decomposition temperature of preferably used ammonium phosphate and ammonium polyphosphate is 275 ° C., and the decomposition of polyhydric alcohols of pentaerythritol, dipentaerythritol, tripentaerythritol and polypentaerythritol preferably used as polyhydric alcohols Since the temperature is 260 ° C., the decomposition starting temperature of the synthetic resin is 250 ° C. or more, and the one in which 50 wt% or more and 90 wt% or less of the total solids are decomposed by 300 ° C.
A sufficient foam layer can be formed. In addition, the foamed layer becomes brittle due to excessive foaming, and the foamed layer is less likely to fall off.

The flame-retardant foaming agent generates an inert gas such as ammonia gas when the cured adhesive is heated, and at the same time lowers the temperature of the painted surface by an endothermic reaction. It is preferable to use ammonium phosphate and / or ammonium polyphosphate as the flame-retardant foaming agent. The decomposition temperature of ammonium phosphate and ammonium polyphosphate is 275 ° C., and the dehydration and condensation reaction with a polyhydric alcohol described later in the temperature range of 250 ° C. to 300 ° C. proceeds efficiently.

The polyhydric alcohol is a component which is dehydrated and condensed with the flame-retardant foaming agent and forms a foamed layer by the decomposition gas of the flame-retardant foaming agent. Examples of polyhydric alcohols include pentaerythritol, dipentaerythritol, tripentaerythritol, polypentaerythritol, triethylene glycol, sorbitol, resorcinol, glycerin, trimethylolmethane, trimethylolpropane, diethylene glycol, propylene glycol, hexamethylene glycol, and the like. No. Among these examples, in order to decompose at substantially the same temperature as the flame-retardant foaming agent and form a foamed layer, the decomposition temperature is 260 ° C.
, It is possible to form a more stable foam layer, pentaerythritol, dipentaerythritol,
It is preferable to use a polyhydric alcohol selected from tripentaerythritol and polypentaerythritol. Further, dipentaerythritol is more preferably used because of its excellent water resistance.

The foamed refractory adhesive may further contain a nitrogen-containing foaming agent. This nitrogen-containing blowing agent is dehydrated and condensed with a polyhydric alcohol to generate a decomposition gas,
It is a component that forms a foamed layer. Examples of the nitrogen-containing blowing agent include dicyandiamide, azodicarbonamide, melamine and derivatives thereof such as trimethylolmelamine, hexamethylolmelamine, and hexamethoxymethylmelamine, urea, butylurea, dimethylurea, guanylureaphosphate, and aminoguanylurea. Urea formaldehyde, aminoacetic acid, guanidine and the like. Among these nitrogen-containing blowing agents, the decomposition temperature is 37 in view of the control of two-stage foaming in which the expansion ratio is increased again at a temperature different from the decomposition temperature of the flame-retardant blowing agent.
Preference is given to using melamine or its derivatives at 0 ° C.

The content of the nitrogen-containing blowing agent is preferably in the range of 60 to 180 parts by weight, more preferably in the range of 80 to 150 parts by weight, based on 100 parts by weight of the polyhydric alcohol. If the amount is less than 60 parts by weight, a sufficiently foamed foam layer cannot be obtained. If the amount is more than 180 parts by weight, the foamed layer may fall off due to excessive foaming, and may have a weight of 80 to 150 parts by weight. In the case of the range, the foaming of the foamed layer is sufficient, and the foamed layer is well balanced without falling off.

Further, it is possible to use one in which at least one of the flame-retardant foaming agent, polyhydric alcohol, and nitrogen-containing foaming agent is microencapsulated. Can improve the water resistance and prevent a decrease in fire resistance performance.

The coating material for microencapsulation is
Melamine, ethyl cellulose, cellulose nitrate, polymethyl methacrylate, polystyrene, epoxy resin, acrylonitrile-styrene copolymer, cellulose acetate phthalate, vinylidene chloride-acrylonitrile copolymer,
It is preferable that it is arbitrarily selected from polyvinyl formal.

Since the coating substance is excellent in water resistance, it can be microencapsulated to be a polyhydric alcohol having hydrophilicity and poor water resistance, a flame-retardant foaming agent, or a nitrogen-containing foaming agent. Can be used. Melamine resin or polystyrene resin is preferably used because of more complete coating, water resistance, strength of the encapsulated product and fineness of the capsule.

The method of microencapsulating a polyhydric alcohol, a flame-retardant blowing agent, and a nitrogen-containing blowing agent includes an interfacial polymerization method, i.
Known microencapsulation methods such as n situ polymerization method, in-liquid curing coating method, coacervation method, interfacial precipitation method, spray drying method, and inorganic wall encapsulation technique can be used, and the coating method is particularly limited. It is not something to be done.

Further, titanium dioxide can be added to the foamed refractory adhesive of the present invention. By the addition of titanium dioxide, the bonding of the foamed layer is promoted by its catalytic effect, and a foamed layer with high shape retention is formed. The crystal forms of titanium dioxide include anatase type and rutile type,
Anatase type titanium dioxide is preferably used. The catalytic effect is further promoted by the anatase type titanium dioxide.

It is also possible to add expandable graphite. Expandable graphite has the property that the compound existing between the graphite layers thermally decomposes when heated and the whole expands. By adding expandable graphite, a thinner and higher fire-resistant adhesive can be obtained. . The coating film to which the expandable graphite is added expands rapidly by heating at the time of fire or the like, thereby improving the heat insulating performance of the foamed layer. Examples of such expandable graphite include graphite acid sulfate, sodium graphite, potassium graphite, halogenated graphite, graphite oxide, aluminum chloride graphite compound, and ferric chloride graphite.

The foamed refractory adhesive of the present invention may contain other components in addition to the above components. Other components can be contained within a range that does not impair the effects of the present invention. Its components include calcium carbonate, clay, silica sand, aluminum hydroxide, alumina,
Fillers and extenders such as silica, inorganic fibers and rock wool, halogen-based, phosphorus-based, antimony trioxide-based flame retardants and defoamers, surfactants such as dispersants, wetting agents, plasticizers, and film-forming agents. Auxiliaries, solvents such as antifreeze, coloring pigments, metal soaps, stabilizers, thickeners for viscosity and viscosity adjustment, preservatives,
There are fungicides and the like.

The above materials are mixed using a mixing device such as a kneader or a mixer, and a foamed refractory adhesive can be obtained. This foam type refractory paint is applied to an adherend or a surface covering material, and the surface covering material can be attached to the object to be coated. The foamed refractory adhesive can be applied to the adherend or the surface material using a trowel, a roller, a spray, or the like, and the application method is not particularly limited.

The foamed refractory adhesive has no problem as long as it has a coating thickness necessary for sticking the surface material, but is preferably 0.5 mm or more in view of fire resistance. Further, the thickness is preferably 3.0 mm or less from the dry curing of the foamed refractory adhesive. If the thickness is less than 0.5 mm, the fire resistance may be inferior.
When it is thicker, drying and curing may take time.

It is also possible to apply a pretreatment such as a primer or a base adjustment to the object to be coated before attaching the facing material with the foamed refractory adhesive. It is also possible to apply a rust preventive paint or the like. By performing such a pretreatment or the like, it is possible to improve the adhesion between the adherend and the foamed refractory adhesive, and prevent rust on the iron portion.

[0032] Examples of the surface covering material include commonly used tiles, stone materials, and wallpaper. This surface covering material is for attaching the surface covering material to the surface of the adherend such as the inner and outer wall surfaces, ceiling, columns and beams of the structure such as a building, or the wall material and ceiling material used for them. This is to improve the protection and design of the structure.

As the surface material, a material having flexibility and waterproofness is preferably used. Examples of the flexible and waterproof covering material include a sheet-like covering material such as that described in JP-A-4-85447, which is composed of a decorative material portion mainly composed of a synthetic resin and a base material portion. Can be Since the sheet-like covering material is lighter in weight than tiles and stone materials, the weight applied to the structure of the adherend is small.

The flexibility may be such as to follow the movement of the structure, and the sheet-like covering material may be a decorative material mainly composed of synthetic resin and a base material made of a fiber sheet or the like. And sufficiently follows the movement. The waterproofness is to prevent intrusion of water such as rainwater into a structure, and to prevent deterioration of the structure by preventing intrusion of water. Some of the sheet-like surface covering materials have overlapping margins that also serve as joints only on two adjacent sides, and when the surface covering material is pasted with the overlapping margins, one side having no overlapping margins in the overlapping margins. Is to be attached. In this manner, one side having no overlapping margin is adhered to the overlapping margin portion, and is laminated and adhered, thereby having waterproofness.

As described above, according to this embodiment, the following effects are exhibited.・ By containing a synthetic resin, a flame-retardant foaming agent, and a polyhydric alcohol, the adhesive applied to the adherend is foamed, thereby improving the heat insulating property of the adherend and improving the fire resistance. It is one that obtains performance and is flexible.

An adhesive applied to the object by applying a foaming fire-resistant adhesive containing a synthetic resin, a flame-retardant foaming agent, and a polyhydric alcohol to the object, and then attaching a surface material. By foaming, the heat insulating property of the adherend is improved, fire resistance is obtained, and the object can be finished with a flexible material.

[0038] Since the surface material has flexibility and waterproofness, it can follow the movement of the structure, and by preventing intrusion of water, deterioration of the structure can be prevented. Is what you do.

Since the synthetic resin is a synthetic resin emulsion, water evaporates when the adhesive is cured, and does not pollute the atmosphere or the like. Furthermore, it is easy to obtain, excellent in physical properties such as water resistance as an adhesive, excellent in workability, and easy to produce an adhesive.

The glass transition temperature (T
When g) is in the range of −30 ° C. to 50 ° C., when the temperature in the atmosphere increases, the attached surface covering material does not shift, and can follow the movement that occurs in the structure, and is attached. Cracks do not occur in the surface material.

The decomposition start temperature of the synthetic resin is 250
℃ or less, 50wt% of total solids by 300 ℃
By decomposing at least 90 wt% or less,
A sufficient foamed layer can be formed by the dehydration condensation of the flame-retardant foaming agent and the polyhydric alcohol, and the foamed layer becomes brittle due to excessive foaming, so that the foamed layer is less likely to fall off and is well-balanced.

When the flame-retardant blowing agent is ammonium phosphate and / or ammonium polyphosphate, the dehydration and condensation reaction with polyhydric alcohol proceeds efficiently.

The polyhydric alcohol is selected from pentaerythritol, dipentaerythritol, tripentaerythritol and polypentaerythritol, so that a more stable foam layer can be formed.

Further, a nitrogen-containing blowing agent can be contained, and since the nitrogen-containing blowing agent is melamine or a derivative thereof, the expansion ratio is increased again at a temperature different from the decomposition temperature of the flame-retardant blowing agent. The two-stage foaming can be controlled.

When the content of the nitrogen-containing blowing agent is in the range of 60 to 180 parts by weight based on 100 parts by weight of the polyhydric alcohol, a sufficiently foamed foam layer is obtained, and foaming is excessive. It is difficult for the foamed layer to fall off due to the above.

The flame-retardant blowing agent, polyhydric alcohol,
By using a microcapsule in which at least one of the nitrogen-containing blowing agents is microencapsulated, it is possible to improve the water resistance of the cured adhesive and prevent a decrease in fire resistance performance.

When the coating material used for microencapsulation is a melamine resin or a polystyrene resin, more complete coating, water resistance, strength of the encapsulated product, and fine capsules can be obtained.

By adding titanium dioxide to the foamed refractory adhesive, bonding of the foamed layer is promoted by the catalytic effect of the titanium dioxide, and a foamed layer having high shape retention is formed.

By adding expandable graphite to the foamed refractory adhesive, it is thinner and has higher fire resistance.

Decomposition of polyhydric alcohols selected from pentaerythritol, dipentaerythritol, tripentaerythritol, and polypentaerythritol, melamine and its derivatives as nitrogen-containing blowing agents, and synthetic resin A temperature of 250 ° C. or less, wherein 50 wt% to 90 wt% of the total solids are decomposed by 300 ° C., and ammonium phosphate and / or ammonium polyphosphate as a flame-retardant foaming agent Thereby, a sufficient foam layer can be formed,
The foamed layer is less likely to be brittle due to excessive foaming, is less likely to fall off, and is well-balanced.

The coating thickness of the foamed refractory adhesive is 0.5 mm to
By being in the range of 3.0 mm, good fire resistance performance is achieved.
Also, the adhesive has good drying and curing properties.

Hereinafter, embodiments of the present invention will be described specifically.
